My: present invention pertains to ratchet wrenches, and contemplates theprovision of a ratchet wrench characterized by the capacity toyieldingly hold and preventdrop- 5 ping or'casual 'displacement of thearticle;

or articles that are being turned through the medium of the wrench. 1 Mynovel wrench"s designed more especially" for holding in" detachablemanner and 19 turning a washer and nut employed, ina certain specialrelation, all of which will be hereinafter-fully described; ;T0 theattainmentfof the foregoing my invention consists in the improvement ashereinafter described and definitely claimed In the accompanyingdrawings forming part of this specification z y M Fig'ure 1 issideelevation illustrating my novel wrenchand also "illustrating a nutheld in the Wrench; f Figurefz is a'view partlyinside elevation andpartly in section, showing a Washer in my-novel wrench. v v 1 Figure 3is a fragmentary longitudinal central section showing bothparts of myimprovement. 7 a

accommodated for the reception and rotaf=tion of the rotary ratchetmember 4 of the "wrench; the said ratchet member 4- provided-- withperipheral'teethfi. My improvements "arecarried by the, said=rotaryrratchet member 4 which in general onalnut designated by 6.
